External Soul Bone, Eight Arms Take Shape

The chance of Soul Beasts producing Soul Bones was extremely low.

So low that even after ten thousand years, Soul Bones remained scarce resources, and most Soul Masters might never see one in their entire lives.

However, the drop rate of Soul Bones was not entirely beyond human influence.

Secret Technique Soul Bones were one method, but wanton slaughter was an evil path in this day and age. After all, the conflict between Soul Masters and Soul Beasts had already accumulated too deeply.

Besides Secret Technique Soul Bones, one could make a Soul Beast experience extreme emotional turmoil before death—hatred or fulfillment. It was said that this could increase the chance of a Soul Bone dropping.

It still did not guarantee a Soul Bone.

But without question, the fact that such a claim had spread meant it had some basis in reason.

Extreme emotions bestowed powerful willpower, and it was not difficult to accept that this had some connection to condensing Soul Bones.

After noticing the hatred and pleading intertwined in the Deep Sea Demon Octopus's eyes, Mu Yuan could not help but think of this.

He subconsciously glanced at Du Busi.

Over the past half month, the island had often echoed with the Deep Sea Demon Octopus's miserable cries.

So Du Busi had done it deliberately.

He was not cruel by nature, nor was he seeking amusement. He had simply noticed that this Deep Sea Demon Octopus had the potential to condense a Soul Bone, and that its hatred toward the two of them had reached a sufficient level, so he had gone with the flow.

"Thank you, Sect Master."

Although no Soul Bone had appeared yet, Mu Yuan was still grateful that the other man had considered his Soul Ring so thoroughly.

Du Busi waved a hand, utterly unconcerned.

In his eyes, there was only the family of the Body Sect.

Since Mu Yuan was a Sect Disciple, he would do his utmost to help him.

It was not that he devoted himself wholeheartedly to every disciple, but his energy was limited, and most of the time he truly could not be bothered to move.

But since he had acted personally this time, these things were merely convenient, and naturally he would not slack off.

After giving his thanks, Mu Yuan looked toward the Deep Sea Demon Octopus.

Taking a deep breath, a bright yellow Soul Ring slowly rose from beneath his feet.

"First Soul Skill, Diamond Demon Body!"

Mu Yuan's body instantly expanded by a full size. His arms bulged with muscle, veins standing out like coiling dragons across them.

"Vajra Subdues Demons!"

Dark Gold flashed in his eyes as Mu Yuan gathered Vajra Power into his right arm.

A Dark Gold phantom condensed around his right arm.

Scarlet light suddenly flared within his right arm, and red-black power surged forth.

Blood Qi mixed with Demonic Qi and rushed out, wrapping around the phantom arm formed by Vajra Power.

Boom!

He threw a punch.

The Deep Sea Demon Octopus was tightly restrained by Du Busi and could not resist at all.

Nor did it intend to resist.

It did not draw upon Heavenly Thunder Power.

It simply allowed the fist phantom to strike its head.

Using Demonic Qi as a guide and Blood Qi as a thread, Vajra Power followed the trail deep into the Deep Sea Demon Octopus's body, crushing everything in its brain like rotten wood.

Bang!

Du Busi released his hand, and the Deep Sea Demon Octopus's corpse fell to the ground.

Noble purple radiance gathered from heaven and earth.

Before long, a purple Soul Ring appeared before Mu Yuan.

Without hesitation, Mu Yuan connected to the Soul Ring with Soul Power, sat cross-legged atop the Deep Sea Demon Octopus's corpse, and began fusing with it.

Du Busi's gaze swept across the Deep Sea Demon Octopus's corpse.

When he saw no Soul Bone, a trace of disappointment flashed through his eyes.

Had all that effort been for nothing?

But in the next instant, the disappointment in his eyes vanished, leaving only astonishment.

He looked at Mu Yuan and discovered that, while fusing with the Soul Ring, Mu Yuan was unconsciously gathering the Soul Power dispersing from the Deep Sea Demon Octopus after its death.

That was Soul Power that did not belong to the Soul Ring.

Behind Mu Yuan, a pattern resembling a Hexagonal Compass formed at his shoulder blades, faintly condensing something.

Du Busi walked around behind Mu Yuan, carefully observed the scene, and fell into thought.

Mental World.

Mu Yuan sat cross-legged in a pitch-black world, black-gold color flowing through his arms.

A closer look would reveal a hint of blood-red brewing within his right arm.

A Deep Sea Demon Octopus spread its eight tentacles and clung tightly to his back.

Mu Yuan felt as though the Deep Sea Demon Octopus were frantically tearing into his back. The pain of bones shattering and flesh ripping pierced straight into his soul.

Just as Mu Yuan thought that was all, a surge of Heavenly Thunder Power rushed into his body from his back.

Boom!

Heavenly Thunder Power ran rampant, sweeping through his Four Limbs and Hundred Bones.

The Demonic Qi dissipated, hidden beneath Vajra Power, while the Blood Qi receded.

Heavenly Thunder Power transformed Mu Yuan's body, connecting his Four Limbs and Hundred Bones.

Yet it did nothing to ease his pain. Instead, it magnified his suffering.

The octopus on his back was like a suction cup, its terrifying pull seeming ready to Devour all of Mu Yuan's flesh, blood, and organs.

Mu Yuan clenched his teeth and guarded his mind.

His will was unwavering.

"Vajra Subdues Demons!"

An angry roar echoed through the endless darkness.

Rumble!

Mu Yuan felt as though something were growing from his back, breaking free from its shell.

Vajra Power and Heavenly Thunder Power mixed together, flowing around his body before finally gathering at his back and bursting out.

When Mu Yuan woke again, it was already evening.

Seeing this, Du Busi handed him a waterskin.

"You brat, you've gained a tremendous opportunity this time."

His eyes were filled with undisguised admiration.

Mu Yuan was not confused. During the Soul Ring fusion, he had already felt it—the thing erupting from his back like a newly born limb should have been a Soul Bone.

Moreover, it was not an ordinary Soul Bone, but an External Soul Bone.

A supreme treasure that Soul Masters dreamed of.

In this era, Hundred-thousand Year Soul Rings and Soul Bones were no longer legends. Experts like Du Busi, Mu En, and Long Xiaoyao possessed more than one set.

Yet not one of them had an External Soul Bone.

"From the perspective of a Body Martial Soul, your former Arm Martial Soul was both important and unimportant when viewed as part of the human body. But now, your arms are no longer merely arms."

Du Busi looked at Mu Yuan, a trace of complexity flashing through his eyes, along with hidden anticipation.

"The Deep Sea Demon Octopus gave you a Soul Bone—an External Soul Bone. It is attached to your back and connected to the arm bones in both arms, your shoulder blades, and your Ribs, as though they are one."

"This External Soul Bone uses Heavenly Thunder Power and Vajra Power to condense six additional arms. Together with your original pair of Hands, you now possess eight arms."

Du Busi's face was full of amazement.

"With this Soul Bone, the parts of your body corresponding to your arms are no longer purely your two arms. I feel that if you continue cultivating, your back and even your entire torso may become part of your Martial Soul."

Arms were unimportant?

With more arms, the area of the corresponding parts of the human body became broader.

Du Busi could only say that Mu Yuan had provided the Body Sect with a new line of thought for cultivating Body Martial Souls.

"Perhaps I can try it as well..."

Extend the arms until they encompassed the torso.

Without question, Mu Yuan's Martial Soul had taken a great step forward.

Du Busi's own Martial Soul was his body. It appeared complete, but in truth, it was not.

His body only corresponded to his physical form; it had yet to encompass his soul.

"If I can make my own Body Martial Soul encompass my soul, truly making my Martial Soul complete, condensing the Second Soul Core will be but a thought!"
